The division (
/) operator produces the quotient of its operands where the left operand is the dividend and the right operand is the divisor.
x / y
/ operator is overloaded for two types of operands: number and BigInt. It first coerces both operands to numeric values and tests the types of them. It performs BigInt division if both operands becomes BigInts; otherwise, it performs number division. A
TypeError is thrown if one operand becomes a BigInt but the other becomes a number.
For BigInt division, the result is the quotient of the two operands truncated towards zero, and the remainder is discarded. A
RangeError is thrown if the divisor
0n. This is because number division by zero returns
-Infinity, but BigInt has no concept of infinity.

Division by zero
2.0 / 0; // Infinity 2.0 / 0.0; // Infinity, because 0.0 === 0 2.0 / -0.0; // -Infinity 2n / 0n; // RangeError: Division by zero
